ECO4 Solar Panel Grant 2026
The Energy Company Obligation (ECO4) runs until 31 December 2026. It is funded by energy suppliers and aimed at low-income and fuel-poor households. The supplier decides which measures to fund after a retrofit assessment, so solar panels are never guaranteed.
ECO4 is not a grant with a fixed amount. Measures might be funded in full or in part; the supplier decides, and you may be asked to contribute. Only agree once you have a contract.
- Someone in the home gets Universal Credit, Pension Guarantee Credit, Pension Savings Credit, Income Support, income-based JSA, income-related ESA, Child Benefit (income limits apply) or Housing Benefit
- Owner-occupied home rated EPC D to G
- Privately rented home rated EPC E to G, with the owner's permission
- A participating council can also refer some low-income households or people whose health is made worse by a cold home (ECO4 Flex)
- Eligibility does not guarantee installation, or solar panels in particular
- Owner-occupied homes rated EPC A to C
- ECO4 funding cannot be combined with other government grants for the same measures
How the application works
01
Contact a council or supplier
There is no single application form. Contact your local council, if it takes part, or any obligated energy supplier, not just your own.
02
Retrofit assessment
An assessment decides which measures suit the home. Installers must be TrustMark registered.
03
Check who you are dealing with
Installers or agents may contact you directly. Check with the council or the supplier they claim to represent before you agree to anything.
04
Paying yourself instead
If you are not eligible, home solar panels and batteries carry 0% VAT until 31 March 2027, then 5%. We quote every line up front.
